Page 4: General Description
1 GENERAL DESCRIPTION The SILBUS repeater type SILBUS-A2WCCT2 is an explosion protected DIN rail-mounting module that is used to increase the distance in a Dupline or SILBUS network. The repeater can also be used as a ‘power booster’ in a section of a network that has many line powered field devices connected to the network. -

4 OPERATING INSTRUCTIONS The repeater type SILBUS-A2WCCT2 does not require any operator action to operate once it has been installed within an IP54 host enclosure and wired correctly. The repeater introduces a delay of one Dupline / SILBUS scan when transferring channel pulses from the secondary network to the primary network. -
Page 7: Terminations And Connections
5 TERMINATIONS AND CONNECTIONS All connections to the repeater are via cage-clamp terminals around the perimeter and near the front of the DIN rail mounting enclosure, these terminals can accommodate up to 4mm conductors. There are 6 possible connections to the repeater; these are shown in the following tables and diagrams: 12V I.S. -
